Hi Lawnboy.
I don't claim to understand in depth how lenticular lenses 'work' to create 3D but I can't see any obvious objection to your proposal. Equally though, you could have just a vertical grille arranged so its lines could cut off one or other of the rasters to each eye. You'd need to view at the correct distance though. I think Baird used this arrangement at one point.
I have attempted 3D NBTV in the past. The rig shown here switched between left and right frames alternately. There was of course massive 6¼Hz flicker but I did find the brain's two hemispheres would integrate the left-right flicker, making it look like 12½ Hz again!
I also have used lenticular lenses before, but only in an invention called the 'Copycoder'. Here, the lenses are stacked side-by-side and (simplifying slightly) they are twice as thick as their focal lengths - so a mirror image of each lenticular section is created at a magnification of x1. Twist the array by 40 degrees and - bingo!
